One-Piece Swimming Pools Built for Speed and Simplicity

What Is a One-Piece Pool?

A one-piece pool (also known as a fibreglass or pre-moulded pool) is a fully formed shell manufactured in a controlled environment and delivered to your property ready to install.

Unlike traditional builds that take weeks or months, one-piece pools are designed for rapid installation — often completed within just a few days of delivery.

Each pool shell is reinforced with high-quality fibreglass or composite materials for exceptional durability. The result is a watertight, smooth-finish pool that looks stunning, requires minimal maintenance, and can be installed almost anywhere with suitable access.

With a variety of sizes, shapes, and step configurations available, one-piece pools offer the perfect combination of speed, reliability, and visual appeal — ideal for homeowners who want to enjoy their new pool without lengthy construction timelines.

Why Choose a One-Piece Pool

• ⚡ Fast Installation: The pre-moulded shell means your pool can be in the ground and ready to fill in days, not weeks.

• 💧 Seamless Finish: Manufactured in one continuous piece for superior watertight integrity and a sleek look.

• 🌡️ Energy Efficient: Smooth, insulated fibreglass helps retain water heat and reduce running costs.

• 🛠️ Low Maintenance: Non-porous surfaces resist algae and require fewer chemicals.

• 🏡 Compact Access: Ideal for gardens with restricted space or time-sensitive projects.

1. Design & Delivery
   Choose your preferred shape and size from a curated selection. Once confirmed, your pool is factory-built and delivered to your site on a specialist trailer.

2. Ground Preparation
   We excavate and prepare a stable, level base with reinforced concrete or gravel bedding, ensuring perfect alignment and drainage.

3. Positioning the Pool
   The pool shell is carefully craned into position, levelled, and backfilled to secure it in place.

4. Plumbing & Finishing
   Filtration, heating, and lighting systems are connected, then we complete the surrounding paving, decking, or landscaping for a fully finished look.

This streamlined process makes one-piece pools one of the fastest, cleanest, and most efficient pool types available today.
